G. Scumimnn, at the An object of the invention is to provide a glass of the character and for the purposes mentioned which may be economically manufactured and which will diffuse the rays of light projected through the glass in a satlsfactory and efficient manner.

Another object of the invention is to pro- Y vide a glass of the character and for the purposes mentioned which-may be manufactured economically. Y

,With the foregoing and other objects in view, which do not require specific mention and which will appear from the following description in which reference is made to thereof.

the drawing, I have produced a glass ,of

which Figure 1 is a front view, and Fig. 2 is a cross sectional view on the line 2-2 of Fig; 1.

s shown my improved headlight glass comprises a piece of glass which may be 0 any, desired shape and. dimensions. The glass is of the rough-rolled or hammered construction having on one side thereof a series of undulations formed by the rollers by which the glass is rolled in the manufacture thereof. The undulations comprlse the rounded raised portions 1 extending'the full width of the glass and separated by curved bottom depressions v 2 extending the full width of the glass, and being formed by the rollers employed to. roll the glass during the manufacture thereof. h The opposite side'Of the glass is of the hammere construction having numerous closely formed rounded elevations 3 giving this side of the glass a spotted appearance. These elevations are formed by the rough or hammered surface of the table u on which the glass is supported while the g ass is beingrolled during the .manufacture Preferably the undulations, comprising the raised portions 1 and the depresissouri,

sions or spaces 2 between them, are of con- Patented Sept. 20, 1921.

siderably greater width respectively than the cross sectional width of the elevations 3, as Wlll be readily understood by reference to 1*1g.'2 1n Wl'llCh a cross section of'the glass 1s shown. In the manufacture of my improved headlight glass a central space 4' of any desired shape and size is provided, and around the central space the glass is frosted forming a frosted area 5. The frosting of the glass may be effected in any known manner, as by subjecting the glass to a sand blast ,or by grinding the area to .be frosted. This leaves a clear line of demarcation 6 separating the frosted area from the central unfrosted area of the glass, and sli htly reduces the thickness of the froste portion wlthout wholly removing the elevations 3.

s A headlight glass constructed as above described wholly eliminates the objectionable glare andbrilliancy of the light projected through the glass, softening and diffusion of the light which is and accomplishes thenow desired in connection with automobiles,

and other vehicles. The appearance of the undulations 12 on one side of the glass and the elevations 3 on the other side of the lass f diminishes the glare and 'brilliancy o the light projected through the central ortion 4..

It is obvious that t e glass may of any desired thickness or size,and that the dimensions and. shape of the central area maybe varied in accordance with the needs and preferences of the user. I do not restrict m self to unessential features in this or ot er particulars sire to secure b Letters Patent, is

1 A headlig t glassof the character described, comprising a glass plate having series of undulations over the entire surface of one side thereof, and having outwardly rounded, raised portions forminga spotted arrangement over the entire surface of the opposite side, the cross sectional width of the but what I'claim and deundulations be ng greater than the cross sectional width of the rounded raisedportions,

and the border of the glass being of less translucent character than the central por-.

tion of the lass.

2. A hea light glass of the chara ter deioo ' scribed, comprising a glass plate having a side, the cross sectional width'of the rounded bordering portion of less thickness than the raised portions being less than the cross seccentral portion, said plate having undulational Width of the undulations, and said 10 tions over' the entire surface of one side thinner bordering portion of said plate be 5 thereof and having outwardly rounded ing of less translucent character than the raised portions forming a spotted arrangecentral portion.
